Hi guys and gals,my 32 bit XP was a bit mangled by a virus so I thought I'd upgrade to a 64 bit OS.I'm running a Q9550 on an ASUS P5Q pro with 4GB of OCZ plat. RAM with a 1GB 9800 Pro.I have a copy of XP64 pro SP1 that I had not installed due to a lack of anti virus supporting that OS.Am I better off installing that sys or spending the money and getting W7 64 pro?this maching is for running FS9 and FSX but is also used for browsing, Call of Duty etc.Will going to 64 bit give me better FS perf, less blurries smoother perf. etc?ThanksStan

You will get a million different answers o this question because it is system dependent.Personally I moved a short while ago on my FS9 partition from WinXP-x86 to Win7-X64.I'm happy with the performance etc, but my feeling is that FS9 ran under WinXP (marginally) better, a bit more fluent.However if you go to X64 OS anyway, I definately would go for Win7-X64. But as I said, your mileage may vary.
